Method

StringarrayToCommaList(Object[] array)
Format an array of Object as a list with commas, like "apples, oranges, and bananas"); XXX Should have a boolean for the final comma :-) 
StringBuffer sb = new StringBuffer();
for (int i = 0; i < array.length; i++) {
    if (i > 0 && i < array.length - 1) {
        sb.append(',');
    if (i > 0) {
        sb.append(' ');
    if (i == (array.length - 1)) {
        sb.append("and ");
    sb.append(array[i]);
return sb.toString();
StringarrayToCommaList(String[] array)
Converts an array of strings into a comma seperated string. 
return arrayToList(array, ",");
ListarrayToList(final T... items)
array To List 
return Arrays.asList(items);
StringarrayToList(int[] intArr, int cnt)
array To List 
return arrayToList(intArr, 0, cnt);
ListarrayToList(Object[] objs)
array To List 
if (objs == null)
    return null;
List ret = new ArrayList(objs.length);
for (Object obj : objs) {
    ret.add(obj);
return ret;
ArrayListarrayToList(String... stringArray)
Retrieves an array list containing the contents of the provided array. 
if (stringArray == null) {
    return null;
ArrayList<String> stringList = new ArrayList<>(stringArray.length);
Collections.addAll(stringList, stringArray);
return stringList;
StringarrayToList(String[] array, String delim)
Converts an array of strings into a delimeter seperated string. 
String result = "";
for (int i = 0; i < array.length; i++) {
    result += array[i] + ((i == (array.length - 1)) ? "" : delim);
return result;
ListarrayToList(String[] str)
array To List 
List list = Arrays.asList(str);
return list;
ListarrayToList(T[] array)
Puts varargs in a mutable list. 
List<T> list = new LinkedList<>();
Collections.addAll(list, array);
return list;
ListarrayToList(T[] t)
array To List 
if (t == null || t.length == 0) {
    return new ArrayList<T>(0);
List<T> list = new ArrayList<T>(t.length);
Collections.addAll(list, t);
return list;
